N 1TH@ STATES @FFQE RALPH FRANKLIN THACKSION, OF ANDERSON, SOUTH CAEGLINA.

BOBBIN-SUPPORTER FOR LOGMS.

Application led April 1S, 1918.

.To all whom t may concern:

.Be it known that I, RALPH F. THAcK- s'roN, a citizen of the United States, residing at Anderson, in the county of Anderson, State of South Carolina, have invented a new and useful Bobbin- Supporter' for Looms; and I do hereby declare the following to be a full7 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an. improved bobbin supporter for looms, particularly the Draper type of loom, and one of the objects of the invention is to provide a device of this kind having improved simple, eliicient and practical features of construction.

A further object of the invention is to provide an improved bobbin supporter and means for preventing the bobbin supporter from tilting excessively, in fact to prevent the bobbin supporting end of the supporter from moving too low and hanging. on the edge of the shuttle box.

A further object of the invention isthe provision of yieldable means for the bobbin supporter, and means for adjusting and reg ulating the limiting of the bobbin supporter.

' In practical fields the details of construe tion may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts as hereinafter set forth, shown in the drawings and claimed.

1n the drawings Figure 1 is a view in section through a portion of a cylinder battery of a loom preferably a Draper type of loom, showing the application of the bobbin supporter.

Fig. 2 is a plan view of the bobbin supporter, showing the opposite sides of the cylinder battery in section. l

Fig. 3 is a perspective view of the bobbin supporter detached. y

Referring more especially to the draw ings 1 designates a conventional form of' cylinder battery, for the reception of the bobbins 2, and 3 denotes a shuttle box, and

plan view is substantially U-shaped. This `bobbin supporter 10 has its two arms substantially midway their ends provided With opposite openings 11., to receive the pivot pin 6. The end portion 12 of the arm 13 of the supporter is constructed to engage the head of the bobbin. In fact the end 12 is provided with a plurality of grooves 13 to engage the usual rings 14; of the bobbin. The other arm l5 or' the bobbin supporter is defiected or disposed at an angle to the arm 13, and is provided with a bifurcation 1.6. Carried by the side of the frame 9, (which incases the battery) is a forked arm A17. A rod 18 is disposed between the forks and one end of this rod or bolt designated by the numeral 19 engages the bifurcation 16 of the arm 15 of the bobbin supporter, there being a nut 2O on the end of this rod or bolt, whereby as the bobbin is struck by the hammer end 2l of the transferrer, the bobbin supporter is rocked upon its pivot 6, against improved tensioning means, as Will appear later. When the bobbin supporter is rocked, the bobbin is transfered or discharged from the battery -to the shuttle box. The end 22 of the rod or bolt is provided with a head 23.. A tubular casing24= is mounted upon the rod or bolt with its curved end 25 in 'contact with the head 23. A. .second tubular casing 26 telescopes into thecasing 24. At the end 25 of the casing 24 a shoulder 27 is provided to limit the inwardly'telescoping action of the inner casing 26. The interior surface of the casing 26 is spaced from the rod or bolt 18 as j ing the rod yor bolt is a coil spring 33.v A

34 extends telescopically into casing 26, in contact with thel coil spring the tubular at-its interior end.l The other 29. The casing 211 has a threaded opening 37 in its wall forthe receptionof asset screw or bolt 36, which engages the outer surface of the casing 26 for holding the same in different 'adj usted positions relative to the cas,

ing 24. 'lt 'is to be seen 'that when thadiam- '10 the spring 30 its proper mer end of the transferrer strikes the bobbin and' transfers or discharges the same from the battery, the bobbin supporter will be rocked upon its pivot. The arm 15 will 5 then pull upon the rod or bolt, which will compress the spring 34, and the spring 3B will expand. The casings will have been adjusted-as required so as to accommodate the movement of .the supporter, and when 3ft is compressed, the casing 26 will contact with the forked arrnand. limit the bobb-in supporter in its tilting' move ment, and consequentlyprevent the bobbin supporting end of the arm 13 from 'moving 15 too far and jreventing it from hanging on the edge of t e shuttle box. Itis to be noted that by adjusting the inner casing 26, the tilting actionof 4the bolfbin supporter may be varied, according to the dierent diameters of bobbin heads. However', when uniform bobbins are employed in connection with the loom the inner casing 26 maybe 'either dispensed with, or its adjustment not used, and in this case the nut QOmay be adv justed to regulate the head 23 of the bolt relative to the forked arm, whereby the casing 24 (in case the casing 26 or its adjust- I ment are eliminated) may contact with the forked arm,- so as to limit the supporter in position, in order that it will not hang on the edge of the shuttle box. n

Fig. 5 a modified construction of bobbin supporter for looms is disclosed. However,

in this structure the inner casing 2Q is elimi` nated. In fact only a -single casing 2% is employed, and otherwise the structure is the vsame as the structure shown in the other figures.

The invention having been set forth what 40 is clai-med as new and useful is 1. The combination with a bobbin supporter, of a formed arm carried by the frame of the loom, said supporter' having a pair of arms, one for supporting the bobbin, and

thev other having a yielding connection with the forked arm, and means carried by said connection to contact with the forked arm to limit the bobbin supporting arm of the supporter inits downward movement, said yielding connection comprising a rod passe.

ing through the fork of said arm, one end of the rod having a loose connection with one of the arms of the supporter, a cushioning spring between one of the arms of the suplporter andthe forked arm, said rod having` a head, a casing on' the rod adjacent the Las? said connection to contact with the forke arm to limit the bobbin supporting arm vof the supporter in its downward movement, said yielding connection comprising a rod passingl through the fork of said arm, one end of the rod having a looseaconnection with one of the arms of thejsupporter, a

cushioning spring between one of the arms of the supporter and the yforked arm, said rod having a head, a .casing on the rod adjacent the head, a second casing telescoping the first tubular casing, means carried by the iirst tubular casing for holding the second in different relative adjusted positions, and a coil spring telescoping the second casing and interposed between the vsecond casing and the forked arm.

3. The combination with a bxobbin supporter, of a forked arm carried by the frame of the loom, said supporter having a pair of arms, one for supporting the bobbin and the other rbeing' slotted, means rockably mounting the supporter on the'frame of the loom, a rod loosely engaging the slot of the arm of the supporter and engaging said forked arm, means on one end of the rod to hold it in enga-gement with the slot, the other end of the rod having a head, a pair of casings, one telescopically fitting the other 'and mounted on the rod adjacent the head, means carried by one of the casings for holding the inner casing extended toward the forked arm, a pair of coil springs in surrounding relation to -the rod, one on side of the forked arm and fitting telescopically into the inner casing, and the other on the opposite side of the forked arm, and

means .interposed between the last inen-A RALPH FRANKLIN THACKS'ION.
